MECHANISM FOR TRANSMITTING MOTION.

Specification of Letters Patent.

Patented Mar. 12, 1912.-

To all whom it may concern:

Be it known that I, JAMES I-IADCOGK, of 15 Carter Mount, VVhitkirk, near Leeds, in the county of York, England, have invented new and useful Mechanism for Transmitting Motion, of which the following is a specification.

This invention relates to improvements in means or apparatus employed for imparting a continuous or intermittent traveling motion to the parts of a machine.

Hitherto it has been customary to impart a continuous or intermittent traveling motion to parts of a machine by means of one or more endless belts or chains, or the like to which has been fixed the part or parts of the machine requiring to be moved through a cycle or series of stages. In some cases the belts or chains have been arranged to work over pulleys or wheels of suitable construction, and in other cases a number of the parts of the machine have been jointed or linked together to form an endless chain or belt. Further, when chains have been used they require to be supported by a number of short guides, or wheels, or pulleys to retain them in the required working position so as to keep the parts of the machine on a given level. Also formers ,-for bag making machines,carried by a traveling belt or chain capable of working on a track horizontal or inclined have been used in which sprocket wheels have imparted the motion at each of the ends of the track, and the formers have been kept to their work by means of sprocket wheels interposed be tween the two end wheels.

In all the above cases the use of endless belts or chains causes a considerable amount of friction, and by the carriers or carriages being fixed either to the said endless belt or chain, or linked together they do not work smoothly or readily adapt themselves to the contour of the track or periphery of the pulley. Further, a chain in use invariably stretches by wear and tear thereby causing deflection and lengthening between centers of its links, and when placed in, say, a horizontal position any unnecessary upward, or downward, or inward, or outward pressure given to the centers of the chain between the wheels or pulleys causes a deflection. Owing to the number of joints and pins required to form an endless chain there must of necessity be a multiplicity of wearing and frictional surfaces. lVhen the carriages,to which the tools are attached,are fixed to a chain it has been impossible to readily alter their position without rearranging, or uncoupling, or disconnecting the whole of the mechanism, and any wearing or lengthening of the links would cause the carriages to fail to register accurately at the desired point. In machines requiring regularity and rigidity of the carriages, or other part to be moved great difliculty arises in the use of a chain, or of a number of parts linked together, as the only points at which there is anything like rigidity is where it comes in contact with the wheels or pulleys employed to impart the requisite motion.

In this invention the use of one or more chains, or of a number of parts linked together as well as a track, or bearers, or sup ports for the chain or chains, are dispensed with and not only are the above named difiiculties and defects obviated by the use of a fixed metal track or race of any desired shape, but the carriage or other part may be moved inward, or outward, or higher, or lower as may be desired, and provision is also made for each carriage or carrier to be removed at pleasure, as well as for each or any of the carriages, or earners to be accurately centered or controlled in any desired position for any special class of work.

The object of this invention is therefore to provide means whereby the parts of the machine that are to be continuously or intermittently moved, or made to travel from one point to another may be mounted separately upon and made to travel on a race constructed as hereinafter described, and in which a free and independent carriage or supporting piece for the tool or part to be moved is indepemlently operated at given points though the carriages are in contact with each other during the whole of their traversing motion and in which the jointing together of the various carriages or parts is dispensed with.

A method of carrying this invention into practice is shown in the accompanying drawings, in which Figure 1. is a side elevation of a machine with a rectangular race, with two wheels or disks, and one of a number of the carriages or moving parts mounted thereon; Fig. 2. an elevation of the driving end of the machine; Fig. 3. an elevation of the opposite end of the machine; Fig. 4. an enlarged side elevation of the race and the centeringclevice; Fig. 5. an enlarged plan of same; Fig. 6. an enlarged plan of race; Fig. 7. an enlarged longitudinal section of same on line A, B, Fig. 6; Fig. 8. an enlarged section on line C, D, Fig. 6; Fig.9. an enlarged longitudinal part sectional elevation on line E, F, Fig. 5 showing the centering devices out of their locking position and with the end carriage removed; Fig. 10. an enlarged part transverse section of F ig. 9; Fig. 11. an enlarged part longitudinal sectional elevation on line E, F, Fig. 5 showing the centering devices in position, and the end. carriage removed;- Fig. 12. a part transverse sect-ion of Fig. 11; Fig. 13. an enlarged part plan of the race with two of the carriages locked in position; Fig. 14. an enlarged part plan of the race and two ofthe carriages with the looking or centering device disconnected; Fig. 15. an enlarged elevation of a carriage; Fig. 16. an elevation of one end of a carriage; Fig. 17. anelevation of the opposite end of thesame carriage; Fig. 18. a plan of a carriage shown in position when passing around the curved end of the race; Fig. 19. is a part sectional plan on line G, H, Fig. 1.5; Fig. 20. an elevation of centering device when a circular race with only one wheel is employed; Fig. 21. a plan of the same; Fig. 22. an elevation of a hexagonal race and one wheel or disk; Fig. 23. a plan of the same; Fig. 24. an elevation of a machine with a rectangular race, having four wheels or disksfor operating the carriages; Fig. 25. a plan of the same; Fig. 26. a plan of Fig.

Like parts in all the views are marked with similar letters of reference.

According to this invention a metal guide, hereinaftertermed the race of any suitable. length, depth and thickness is employed. The race is made either circular, as shown at Fig. 20, or hexagonal, as shown at Fig. 22, or rectangular, as shown at Figs. 1, 4:, and 24, or of any other desired or convenient shape, such as, say, square, or elliptical, or a combination of two or more of any of the hereinbefore mentioned shapes. The race is arranged to be fixed upon supports -or pillars 2' upon the table a of the machine, which may be supported upon suitablelegs or framework Z). 0 is the driving shaft.

The race consists of two portions, an outer circular, or hexagonal or elongated ring portion d with or without semi-circular or other shaped ends, 6, e, and a correspondingly V shaped inner portion f whichmay also be p the ring portion (Z.

The machine and parts thereof, as show at Figs. 1 to 19 inclusive, are provided with an elongated race with semi-circular ends arranged as hereinafter described.

The top portions cl and f are arranged as shown in the drawings at Figs. 9 and 10 one within theother and connected together by means of suitable brackets or arms h. The two side portions j, 70, and Z, m, of each pore tion of the race are arranged to be parallel with each other, and with suitable spaces between them. The ends of the sides .of each part are united together respectively by semi-circular ends 6, e, and g, g. The

two portions (Z and'f are made of any suitable length, depth and thickness, but the thickness of the parallel sides of the said outer portion 03 is made slightly thinner than its semi-circular ends 6, 6, so as to permit of the carriages n to travel steadily,

readily, and firmlyaround said semi-circular ends. .Inthe perimeter of the, central portion f of the race is cut or otherwise formed a groove 0 of any suitable width and depth;

On the outer portion cl of the race are mounted a number of traveling carriages n, which either wholly or partially fill its per: imeter, and the'carriages are shaped to the requirements of the tools or parts to be carried and they are made of such a length and shape as to permit them when placed in position thereon to embrace, but not to closely fit upon, its outer side d and the top and bottom surfaces thereof. That is to say, each carriage n consists of a sole or base plate p which is made to project outwardly beyond the outer perimeter of the portion d for receiving the various .tools or pads (not shown in the drawings) which, are attached thereto by bolts which pass through the holes 9, 1', provided for their reception.

The inner end of the sole or base plateis also carried lnward and 1ts lnnerend s is turned upward to form a bearing for the.

smoothly when two or more thin bowls or runners are employed instead of one large one. From the top of the'sole or base plate 7 of each carriage an arm 41 is made to project in an upward direction and its upper end 41 is turned inward and over the top of the outer portion d of the race about parallel Two bowls with the sole or base plate p. The turned over portion '0 of the arm 12 is shaped as shown in plan at Fig. 18, with laterally extending ends w, w, having curved wings, the edges of which are thickened to form abutments for like wings w of adjacent carriages when placed upon the race in working position. In order to retain the carriages n in the required upright position a number, say three, vertical rollers 09, y, 2 are employed and arranged to work respectively against the front and back vertical surfaces of the outer portion cl of the race. The rollers 00 and 3 are mounted upon the spindles 1 and 2 between the sole or base plate 0 and the turned over portion v of the arm 22, washers or bosses 3, 1 formed on the said parts of the carriages n or the same may be thickened for receiving the ends of the spindles. The rollers 00, y, are arranged to work against the front of the portion d. The roller 2 is supported pendantly by a headed and shouldered bolt 5 at the back of the portion cl. The turned over portion 11 which supports the bolt 5 is made thickerat 6 for this purpose. In the drawings the spindles 1, 2 and bolt 5 are shown carried in fixed bearings, but if so desired the whole of them may be made adjustable, or the bolt 5 may be mounted in a slot formed for its reception in the turned over portion of the bracket '0. To the under surface of the turned over portion of the bracket '0 is fixed, by any suitable means, a pair of inverted L-shaped brackets 7 8 at suitable distances apart. The horizontal portion of each bracket is adapted to rest and slide upon the upper surface of the outer portion (Z while the vertical portion of the said bracket is employed for supporting a wearing piece 9 retained against the vertical face of the outer portion (l of the race by the adjusting screws 10, 11, and lock nuts 12, 13. A spring 14: is mounted upon a guide pin 15, carried by the vertical portion of the bracket. The tension of the spring 14 retains the wearing pieces against the ends of screws 10, 11. By means of the screws 10, 11, the wearing pieces 9' may be adjusted to the greatest nicety for insuring of the carriages 'n working with smoothness. As each carriage it passes around the semi-circular ends of the outer portion, the carriage is in the position shown at Fig. 18, be clear of the said ends and the carriage will be retained in a working position by the rollers 50, y, 2.

On the top of each carriage n is fixed one or more vertical pins or studs 16 on each of which is mounted a bowl or runner 17 adapted to engage withcorresponding recesses in, say, a pair of wheels or disks 18, 19 arranged at. each end of the race. In the periphery of each of said wheels is formed a number,-say, six, more or less,-of rethe wearing pieces 9 will, when cesses 20 into which the bowls or runners 17 fit. The wheels or disks 18, 19, are respectively mounted on vertical shafts 21, 22. The shafts are carried in suitable bearings provided for their reception in the table a and race of the machine, and a continuous or intermittent rotary motion is imparted to each shaft from the cam shaft 31 of the machine. In the drawings an intermittent rotary motion is arranged to be imparted to the vertical shafts 21, 22 from a cam 23 on the cam shaft 31 through roller 2 1-. mounted upon lever 25 jointed to the framework Z). The free end of lever 25 is connected to one arm of a bell-crank lever 26 by an adjustable rod 27. The bell-crank lever 26 is mounted upon the intermediate shaft 28 which is carried in bearings provided for its reception in the framework 7). In the upper arm of the bellcrank lever 26 is jointed a pawl 29 adapted to engage with a ratchet wheel 30 fixed upon the intermediate shaft 28. On the intermediate shaft 28 is mounted and fixed a pair of miter wheels 32, 33 adapted to gear with miter wheels 34, 35 mounted respectively on the lower ends of vertical shafts 21, 22. A rotary motion is imparted to the cam 31 from the driving shaft (1 by means of spur wheels 36.' On the driving shaft 0 is also mounted the fast and loose pulleys 37, 38. Or, when a continuous rotary motion is required to be imparted to the intermediate shaft 28, then the shafts 28 and 31 may be either geared together, or motion may be imparted from shaft 31 to intermediate shaft 28 by means of chain wheels and chains. On the opposite end of the intermediate shaft 28 to that upon which the ratchet wheel 30 is mounted, is fixed a flanged brake wheel 39 upon which a brake block 410 is made to act. The brake block is mounted pendantly in a carrier 11 having the spiral springs 12 interposed between the underside of the carrier and the top of the brake block. The carrier 41 is fixed to the upper end of vertical rods 43 which rods are carried in bearings provided for their reception in the table a and the inner bracket 14 fixed to framework b. Between the underside of the table a and the upper surface of the bracket 14- is interposed and fixed upon the vertical rods 43 a slide 15 provided with a stud upon which is mounted a bowl. 4.6. The slide 45 and bowl 16 are arranged in such a position that they can be acted upon by the cam 47 which is mounted and fixed upon the intermediate shaft 28. The cam 47 consists of a series of projections adapted to act upon the bowl 416 simultaneously with the carriage n, being made stationary for the tools attached thereto to perform their respective work, and at the same time that one of the centering blocks 18, 19 is made to enter one of the recesses 50, 51 provided for their reception in the under surface of the wheels 18, 19. The blocks 48, 49, which are shaped on their upper surface to fit the tapering recesses 50, 51 in the wheels 18, 19,are mounted upon the vertical rods 52, 53, carried in bearings formed for their reception in the boss 54 projecting upwardly from the inner portion 7 of the race. The vertical rods 52, 53 are made hollow at their lower ends to form the recesses 55, 56, and they are also slotted at 57, 58. Into each of the recesses 55, 56 is passed respectively a vertical pin 59, 60. The lower ends of the pins are each provided. with a collar 61, 62, and the ends are passed through a cross bar 63 by which the pins 59, 60 are carried, and they are secured in position thereto by the nuts 64, 65. The upper ends of the pins 59, 60 are provided with cross pins 66, 67 which work in the slotted portions 57, 58 of the vertical rods 52, 53. Between the ends of the vertical rods 52, 53 and the cross bar 63 are mounted springs 68, 69. These springs are made to encircle pins 59, 60. At each. end of the cross bar 63 is adjustably mounted a plunger or pin 70, 71. The said plungers work in bearings provided in the inner portion of the race and insure the vertical rods 52, 53 working accurately, and are also employed for purposes to be hereinafter described.

An intermittent vertical reciprocating motion is imparted to the cross piece 63 and vertical pins 52, 53 by means of a cam 72 mounted upon the cam shaft 31. lVit-h the cam 72 a bowl 73 is made to engage. The bowl 73 is mounted upon a pin attached to the loop end 74 of an adjustable rod 75 which is adjustably attached at its upper end to the cross piece 63. The upward movement of thecross piece 63, and parts connected therewith, is so timed that the blocks 48, 49 will respectively enter a recess 50, 51 at the point that a carriage is required to be stationary. In order to steady the action of the carriages, and to lock, say, two of them in po sition while they are on the straight or parallel portion of the race, two locking pieces 76, 77 are provided and arranged at suitable distances apart, say, at a distance sufficient so that the curved and recessed portion of each locking piece will embrace the curved portions 78 of two carriages when together, as shown at Figs. 13 and 14. The locking pieces are mounted in a cross piece 79 mounted upon a spindle 80 provided with a bifurcated end 81 in which are mounted two bowls 82, 83. The spindle 80 is mounted in the bearing 84. At one end of the cross piece the spindle of the locking piece is prolonged to form a short spindle 85 which is arranged to be mounted in the bearing 86. The spindle 85 forms a guide pin so as to insure the accurate horizontal reciprocation of the cross piece 79, and parts connected therei ward movement of the cross piece 63, while the other face of pin 87 or 88 is made to act against bowl 82 for withdrawing the cross piece 79 to the position shown at Fig. 14. In the drawings at Fig. 5 two sets of these locking devices are shown, one of which will be operated as just described by pin 87, and the other by pin 88. In some cases it may be found advantageous to operate both sets of locking devices simultaneously by one pin or cam piece and to withdraw them inward together by another cam piece.

The action of the apparatus is as follows :The whole, or a portion only, of the periphery of the race is occupied with carriages n, and when the said periphery is filled with carriages then the curved wings w, w, of each carriage touch a wing of each adjacent carriage, as shown at Fig. 5. The required too-ls having been fixed in position to the sole plate 79 the belt is thrown on the fast pulley 37, which imparts a rotary motion to the cam shaft 31. The rotary motion is transmitted from cam 23 to the pawl 29 which imparts an intermittent motion from cam 23 to the pawl 29 which imparts an intermittent rotary motion to the intermediate shaft 28. From this shaft the rotary motion is imparted to the vertical shafts 21, 22 by means of miter gearing 32, 33, 34, and 35, thereby causing the wheels 18 and 19 to be intermittently rotated. The rotation of wheels 18, 19 by their recesses 20 engaging with the bowl 17 on the top of the portion 7) of each carriage causes the carriages to be propelled along the track.

When the recesses 50, 51 in the wheels 18, 19 come opposite to the blocks 48, 49 the cam 72 will have moved the cross piece 63 up ward for causing the said blocks to enterinto the said recesses, thereby insuring that the rotation of the wheels will cease when this point is reached, and in order to pre-' vent the carriages a passing beyond a desired point simultaneously with the upward movement of the blocks 48, 49, the locking devices 76, 77 are moved,by means of the cam shaped ends of the pins 87, 88,outward and made to engage with the curved portions 78 of a pair of carriages, as shown at Fig. 13. On the descent of the cross piece 63 the cam shaped portions of pins 87 88 will withdraw the locking pieces 76, 77 away from the curved portions 78 simultaneously with the withdrawal of the blocks 18, 49

. from the recesses 50, 51..

At Figs. 20 to 30 inclusive are shown modifications such as alterations in the shape of the race, the number of operating wheels employed, centering device adapted to such alteration, and shape of the carriage, but in all cases the essential features of the invention are maintained, and the driving mechanism is practically the same, consequently the same reference letters and figures are used for like parts.

At Fig. 20 the machine is shown with a circular race constructed of two parts (Z and 7 arranged one within the other as hereinbefore described. \Vhen this shape of race is employed only one operating wheel 18 is required and it is mounted upon the upper end of spindle 21. The centering device in this instance comprises a disk 89 rotatable with the shaft 21 below the table a, provided on its under surface with recesses 90 to receive the centering block 18 mounted upon two pins 59 and 60 having springs 68 and 69 surrounding the same. The pins 59 and 60 are mounted in the bracket 91 fixed to the lifting rod 75. The lifting rod 75 is attached at its lower end to the loop end 74 which is operated by cam 72 and bowl or runner 73 as before described. The upper end of the lifting rod 75 is provided with a cross piece 63 in which are mounted two center pointed pins 87 and 88, having springs 92 and 93 arranged thereon. The center pointed pins take the place of the pins with cam shaped ends previously described. The center points of pins 87 and 88 pass into recesses provided for their reception in portion 8 of each carriage, and thus dispense with the locking pieces 7 7 and parts connected therewith. In this arrangement one or more carriages n are placed upon the race. Although only one set of locking and centering devices is shown at Fig. 20, yet when required a second set may be provided on the opposite side of the machine.

Figs. 22 and 23 show a machine with a hexagonal race with curves at the juncture of the angles and in which the arm, or portion 79 of the carriage n is dispensed with, and a flange 94: is employed in place thereof, in order that a bag forming device or other tool or holder may be readily attached to the carriage as circumstances require. In other respects the other parts of the carriage are the same as described for Figs. 1 to 19. Instead of providing the wheel 18 with semi-circular recesses 20 they are shown in this arrangement to be slotted. The locking and centering devices are the same as those described for Figs. 20 and 21. When a polygonal race is used, the wheel 18, centering and locking devices may be of a similar construction to those described and shown for Figs. 20 and 22.

At Figs. 24 to 26 a machine is shown with a rectangular race with four curved corners in which are mounted a corresponding number of operating wheels 95, 90, 97 98 mounted upon the upper ends of vertical shafts 99, 100, 101, 102. The said wheels and shafts are of a similar construction to wheels 18 and 19 and shafts 21 and 22. The vertical shafts 99 and. 102 are respectively geared by bevel wheels 103, and/10 1 to a transverse horizontal shaft 105 carried in bearings provided for their reception in the f 'an1ewor I). In like manner vertical shafts 100 and 101 are geared by bevel wheels 106 and 107 to a second transverse shaft 108. The shafts 105 and 108 are geared by helical or skew wheels 109 and 110 to the shaft 28 so that motion is simultaneously imparted to each of the operating wheels. In this arrangement a pair of centering devices attached to a triangular shaped cross piece l11,which takes the place of cross piece 63,-operated by a cam 72, runner bowl 73, and lifting rod 7 5 is provided at each end of the machine for each pair of the said wheels that are operated by the shafts 105 and 108.

At Figs. 27 and 28 is shown a carriage and wheel locking and centering device of a similar construction to that described and shown at Figs. 1 to 12 inclusive, only in this instance three locking pieces 76, 77, and 112 are provided and made to act upon three carriages a at the same time instead of on two carriages. In all other respects and mode of operation they are the same as described for the said figures. This form of locking device is very suitable for the machine shown at Figs. 24: and 25.

It will readily be understood that the parts shown but not described for Figs. 20 to 30 are of a similar construction and act in the same manner as those described for Figs. 1 to 19. Also the shape of the race and the number of carriages and operating wheels and parts connected therewith may be respectively varied or altered or increased as circumstances require.

The herein described apparatus is particularly applicable for labeling machines and for gumming the labels of labeling machines,in which case the gum pads will be adjustably attached to the sole plate by any convenient means so that after the pad has "faces, means for connecting and retaining said'parts of the race in proper relation to each other to form a rigid support and H :guide, and carriages adapted to travel on said race.

2. In a machine of the character described, an integral race way therefor comprising an outer part, an inner part spaced from the outer part, connecting means between said parts, said outer part having parallel vertical outer and inner bearing sur faces, and the inner part having a vertical face provided with a recess extending entlrelyaround sald part said race formlng a rigid unitary support and guide, and car- I riages adapted to travel on said race.
